Advanced modeling of an exploding flux compression generator using lumped element models of magnetic diffusion

Summary form only given. This paper describes an advanced PSpice model, which is used to complement the experimental work on explosive flux compression generators. This work is conducted at Texas Tech University in the framework of a MURI program. The results from the model are compared to two different generator designs. To achieve better fidelity of the model, the effect of transient current diffusion into the conductors of the generator is modeled by using a ladder network with many concentric layers of each current carrying conductor. For the optimum accuracy, the spacing of the concentric layers is closest at the surface of the conductor. The paper shows the results of the calculations for the various models and compares them with experimental data.
